9、03 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS AU 165a:1990 ii BSI 10-1999 Foreword This British Standard has been prepared under the direction of the Automobile Standards Policy Committee and supersedes BS AU 165:1977, which is withdrawn. It establishes a standard of performance to ensure the saf
10、ety of jacks supplied with passenger cars and light vans for the purpose of changing wheels and fitting snow chains as recommended in the vehicle manufacturers manual. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsibl
11、e for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 4, an inside back cover and a back cover. This standard has been up
12、dated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

13、10-19991 1 Scope This British Standard specifies requirements for the materials, finish and safe performance of jacks supplied as original equipment with passenger cars of the European Communities classification category M1 and light vans of the European Communities classification N1 (see Appendix A
14、). 2 General 2.1 The jack shall be suitable for locating at the jacking points as specified by the vehicle manufacturer and shall be capable of being operated without fouling any part of the vehicle with the doors closed. 2.2 It shall not be possible to raise the vehicle with a jack that has been in
15、correctly assembled from its component parts. 2.3 Means shall be provided to prevent over-travel of the jack. 2.4 Instructions for the safe use of the jack shall be provided. 2.5 Written instructions for the use of the jack shall be provided in the vehicle manufacturers instruction manual, together
16、with the following information. NOTEIt may be in a style compatible with the remainder of the vehicle manual text. a) The vehicle jack is only for wheel changing and snow chain attachment (if appropriate). b) Do not place any part of the body under the vehicle when the vehicle is supported by the ja
17、ck alone. Note that it is very dangerous for users to go underneath a vehicle supported only by the vehicle jack. For repair work where the user needs to go underneath, special vehicle supports are to be used. c) Use chocks when stopped on a hill or cambered road. Seek advice on the number, position
18、 and placement of chocks from the manufacturers handbook. Note that the jack is designed only for use on a gradient of less than 8 % and a camber of less than 5.5 %. d) When using the vehicle jack for wheel changing at the roadside: 1) use hazard lights; 2) apply the handbrake; 3) place gears in “1”
19、 or “Reverse” on manual gear boxes, or “P” on automatic transmissions; 4) occupants should leave the vehicle; 5) place the jack at the placement position advised by the vehicle manufacturer; 6) give consideration to advice for jacking on soft ground; 7) do not run the engine when the vehicle is jack
20、ed up; 8) loosen wheel nuts slightly prior to jacking up the vehicle; 9) only use the supplied jack with the vehicle make and model marked on the jack. e) When wheel changing at the roadside: 1) clean the brake drum/mounting flange before fitting a wheel; 2) screw up the wheel nuts before lowering t
21、he vehicle; 3) finally tighten the wheel nuts, to the manufacturers recommended torque, after lowering the vehicle. f) Stow the jack in its stowing point or in a covered container in the vehicle. 3 Materials Strength and other essential physical properties of the component parts of the jack shall be
22、 adequate for use with the vehicle with which it is supplied. All castings, which shall be in accordance with the appropriate British Standards, shall be of uniform quality, free of blow holes, porosity, hard spots, shrinkage, cracks or other deleterious defects which might adversely affect the inte
23、nded use. Processes such as peening or plugging shall not be used on castings or forgings for reclaiming any part of the jack. Lubricants, hydraulic fluids and paints shall be compatible with seal materials, where seals are used. 4 Finish All cast, forged, moulded or welded parts shall be free of sa
24、nd, dirt, fins, scale, flux and other harmful extraneous materials. All external surfaces shall be free of burrs, fins and sharp edges. At the delivery stage the surfaces shall be protected against corrosion, and moving parts shall be lubricated as necessary. 5 Dimensions When tested in accordance w
25、ith Appendix B, the jack shall have adequate extension for use on the vehicle with which it is supplied.

26、 effort It shall be possible to perform the jacking operations described in Appendix B by applying a force that shall not exceed the following values: a) 250 N for jacks operated by up and down lever action; b) 125 N for all other types of jack operation. 6.2 Accidental operation At any point over i
27、ts full travel while raising or lowering the vehicle, the jack mechanism shall not operate independently when the operating force is removed. 7 Stability When tested in accordance with Appendix C, the jack shall support the vehicle without the vehicle coming off the jack. 8 Durability When tested in
28、 accordance with D.2 there shall be no undue wear or permanent deformation of either the jack or the handle and the operating force measured after the tenth cycle shall differ from the fiftieth lift by not more than 10 %. 9 Overload When tested in accordance with D.3 the jack shall not collapse and
29、the permanent deflection shall be not more than 5 % of the height measured at D.3 d). 10 Marking The jack shall be permanently and indelibly marked in accordance with type 8A of BS 4781-1 and BS 4781-2. The marking shall include the following information: a) the make and model of vehicle for which t
30、he jack is intended; b) the number and date of this British Standard, i.e. BS AU 165a:19901); c) a warning sign or other indication to illustrate that the operating instructions are to be found in the vehicle handbook. 1) Marking BS AU 165a:1990 on or in relation to a product represents a manufactur
31、ers declaration of conformity, i.e. a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The accuracy of the claim is therefore solely the responsibility of the person making the claim. Such a declaration is not to be confused with third party certific
32、ation of conformity, which may also be desirable.

34、he jack B.1 Load the vehicle to the manufacturers maximum gross vehicle weight (GVW), less 100 kilos at the drivers position, immobilize it in accordance with the manufacturers instructions, and stand it on a level concrete surface or equivalent. B.2 Locate the jack correctly at each jacking point,
35、with the nearest tyre completely deflated to give the least favourable conditions. B.3 Lift the vehicle off the ground to provide sufficient clearance between the ground and tyre to fit the spare wheel, for all tyre sizes specified by the vehicle manufacturer. B.4 Inflate the spare wheel tyre to the
36、 maximum specified pressure. Appendix C Tests for stability C.1 Use a new jack for each of the procedures in C.2, C.3 and C.4. C.2 Load the vehicle to the weight given in B.1. Apply the parking brake. Using all available jack travel at any jacking point, apply a longitudinal force of 250 N to the ve
37、hicle in both directions separately followed by a lateral force of 250 N in both directions. Apply the force approximately 60 cm above the road surface. C.3 Load the vehicle to the weight given in B.1. Park the vehicle on a surface having a gradient of 8 1 % and a camber of 5.5 0.5 %. Apply the park
38、ing brake and set the transmission control as instructed by the manufacturers manual. Carry out the jacking procedure given in Appendix B first with the vehicle facing uphill and then facing downhill. C.4 Load the vehicle to kerb weight and repeat stability tests C.2 and C.3. Appendix D Tests for du
39、rability and overload D.1 General Use a new jack for each of the procedures in D.2 and D.3. D.2 Durability test Carry out this test with a new jack and handle equally around the jacking points. Follow the procedure given in Appendix B for 50 jacking cycles. One jacking cycle consists of raising and
40、lowering any wheel. Each jacking cycle may be followed by a cooling period of not more than 5 min. D.3 Overload test Carry out the procedure as follows. a) Set any available means of height adjustment (other than that provided by the normal travel of the jack) to its highest position. b) Where fitte
41、d, render the jacks overload protection device inoperative. c) Raise the head cap to 66 % of its range of travel. d) Mount the jack on a flat, rigid surface and measure the height of that part of the load (test rig or weight) which bears on the headcap, above the flat, rigid surface. e) Apply a forc
42、e equal to 200 % of the vertical force taken by the jack under the conditions of Appendix B, at the location with the highest loading. Apply the test force in the same manner as the service loading. f) Maintain the force for 1 min, then remove the force. g) Examine the jack for collapse, and measure
43、 the height of the load above the flat, rigid surface.
